, Generally stated, the apparatus of the pres ent Invention comprises means for initlally washing the comparatively flat ware, such as dishes, platters and the like; for washing cups, glasses, bowls, knives, forks and spoons; for

scouringand polishing culinary 'metal ware; secondary means for steaming the sand articles to remove any mineral residue left by the evaporation of water, upon the surfaces .of said articles; means for drying the articles; and means for heating water, distributing and spraying cold water, and for drainingparts of the apparatus.

Referring now more particular to the several views of the drawing it will thatthe apparatus is associated with a sink -10 to which is led. a cold vwater'feed pipe 11 r of a water supply system. The feed pipell connected by a pipe 12 with an water heater 13 including a heating unit 14 and'a tank 15, with which the pipe 12 connects. A suitable cup 16 isprovided and issupported a sectional view taken on the line;

apparent on a suitable'fixed bracket 17. The cup 16 serves for containing a quantity of soap or other cleaning composition to provide an effective cleaning mixture when combined with hot water. Hot water is led to the cup 16 by a pipe 18 which connects with the upper end of the tank in communication with the interior thereof, and whichextends downwardly and terminates in the cup 16. The pipe 18 has a control valve 19. A hollow spindle 20 is mounted for rotation in bearings provided by portions of the bracket 17. The spindle 20..i s in communication with the cup 16 at its upper end, and the lower end of the spindle is adapted for connection with divers cleaning elements such as brushes and burnishers. A brush 2 1'is shown in the present instance to the bristles of which water is fed through the spindle 20. 9

In order to rapidly rotate the spindle 20 and therefore the brush '21 or other element arranged on the spindle, there is provided an electric motor 22, the shaft of which transmits motion to the spindle 20 by virtue of a pinion 23 on the motor shaft 24, the pinion 23 meshing with the pinion 25- on a art 26 of a twopart shaft, the part 27 of wh1ch has a gear 28 which meshes with a gear 29 on the spindle 20. The shaft parts 26 and 27 are respectively mounted in bearings 30 and 31. A suitable clutch 32 is employed in conjunction with the shaft parts 26 and 27. The said clutch includes a yoke lever 33 which serves for manipulating the clutch for causing thev rotation of the spindle 20 and for stopping the rotationthereof. The articles to be washed, cleaned or burnished are held against them- After the initial-washing of the different articles, they are placed in a cabinet or casing 34-by the use of suitable racks (not shown) although the casing willinclude suitable supports for the racks or for some of the articles. The cabinet or casing 34 is arranged above the sink 10 and has suitable doors 35 which afford access to the interior of the casing. Arranged within the casing 34 are interconnected water distributing pipes 36 which are perforated for the purpose of spraying water against the articles arranged in the casing, The pipes 36 have connection as at 37 with a two-way control valve 38 which is connected with the feed pipell as at39. A faucet 40 is also connected with the valve 38. The valve 38- may be operated to allow water to pass from ranged in the casing through a drain- 47 into the sink -tor is caused to operate.

cold water, they are subjected to the action of steam which will be generated by virtue of means presently to be described. A comparatively shallow pan 42 is arranged at thebottom of the casing 34. The pan 42 is adapted to hold a quantity of water which is heated by an electric heater 43 arranged beneath the pan 42. riesof covers 44 spaced from each other as at 45 to liberate the steam generated which rises in the casing 34. These covers 44 prevent the water which is precipitated from the sprinkler pipes 36 from entering the pan 42. The water so precipitated enters a gutter 46 surrounding the pan 42 and passes out 10. The steam which rises from the pan 42 condenses on the articles arranged in the casing 34, the condensation forming a film of water on each of the articles, which runs off into troughs or gutters 48 extending from one end of the casing 34-and terminating short of the other end so as to empty into drain tubes 49, the lower one of which has connected therein a two-way valve 50. A short tube 51 is connected with the valve 50 and leads to the pan 42. The valve 50 may be" operated to cause water of condensation to pass from the troughs or gutters 48 into the pan 42 or to allow it to flow into the sink 10.

When the articles have been sufficiently rinsed by the water of condensation produced by the steam, the heater 43 is automatically turned off. This is accomplished advantageously by the use of a thermostat 52 of any preferred type which is arranged at the top of the casing 34 within the same. The thermostat 52 is caused to operate by the steam and heated air escaping through a channel 53 which'communicates with an outlet 54. When the thermostat 52 operates to turn ofi the current flowing to the heater 43, the mo- The shaft 24 of the motor has secured thereto a fan 55 which sends a blast of air upwardly .of the interior of the casing 34. The motor and fan are'ar- 34 and one of the walls of the casing has openings 56 through which air enters the casing to be sent by the fan 55 upwardly. The air forced upwardly in the- ,casing 34 will dry the articles within the. easmg.

In Fig. 30f the drawing there is shown a electrical connection of the heater 13, heater 43, motor 22, and ther- Electric current is sup- Arranged over the pan 42 is a seplied from a suitable source, and may advan tageously be supplied from the alternating current supplied by the public service system. Current is supplied to the heating unit 14 of I the heater 13 by a wire 57 connected with a m of a switch 59 in a wire 60 connected with the other feed wire 61 of the supply circuit. Current is supplied to the windings of the motor 22 by virture of a wire 62 connected with one terminal of the motor winding and the feed wire 58,-the current flowing through the winding of the motor upon closing a switch 63 in a wire connected between the other terminal of the motor winding and the feed wire 61. The thermostatic switch 52 in cludes a contact 64 connected with the feed wire 61, a terminal 65 connected by a wire 66 with one terminal of the coil of the heater 43. The other terminal of the coil of the heater 43 is connected with the feed wire 58. The thermostatic switch 52 also includes a contact member 67 which is pivotally connected with the terminal 65 and is adapted to be moved into engagement with the contact 64 to close the circuit through the coil of the heater 43. A thermostatic member 68 is adapted to coact with the member .67 when the former is subjected toa certain degree of heat to move the member 67 to bridge con tacts 69 and 70 to close the circuit through the windings of the motor v22. This will be followed by opening of the circuit to shut off current to the coil of the heater 43. The contact 70 is connected by a wire 71 with the feed wire 61. V

From the foregoing it will be apparent that, when the switch 59 is closed, water in the tank 15 of 'the heater 13 will be heated coil 14. Soap will be placed in the cup 16.

into the cup 16 producing a sea ply solution which will pass to thebrush 21 t roughthe spindle 20. The switch 63 may then be closed which will start the motor 22. By manipulating the lever 33 the clutch 32 will be operated to cause motion to be transmitted to the spindle 20 which will be rotated, also the brush attached to the spindle 20. The articles to be washed may be held against the brush 21 to be subjected to a cleaning or washing action. After these articles have been washed the switches 59 and 63 may be opened which will cease further heatingof water in tank 15 and also the rotation of the motor 22., The contact member 67 maythen be set by hand to engage the contact 64 to close the circuit throughthe coil of the heater 43 which will heat t in t e casing 34. The valve 38 may then be operated to allow cold water to flow into the because current w1ll be flowing through the pipes 36. The water issprayed and rinses and cools the articles and then drops into the gutter 46 from which it is led to the drain 47 into the sink 10. The valve 38 is then closed. Steam now begins to rise from pan 42and condenses on the articles, forming a film of water thereon which collects and runs off into the gutters 4:8, and thence into the tubes 49 and 51 to the pan 42; the valve 50 being opened for thispurpose. This steaming of the articles will remove any mineral matter held in solution by the water used in .the initial washing operation and subsequent spraying operation. When the articles have been sufliciently rinsed by the condensing steam and have become heated so that steam. no longer condenses upon them, the heater 43 will be turned off by the action of the thermostatic switch 52 which is caused to operate by the steam and heated air escaping through the channel 53 and outlet 54. This action is followed immediately by current being shunted through the windings of the motor to set the same in motion causing the fan 55 torotate. The rotation of the fan Will produce a blast of cool air which Will circulate upwardly in the casing 34 thereby drying the articles. When the temperature in the casing has been reduced to. a certain degree, the thermostatic switch ,52 will again operate to cease the operation of the motor 22. If

found advantageous, any other equivalent means may be used instead of this thermo-. static switch as a means of performing the functions described.

It is to be understood that divers cleaning elements may be applied to the spindle 20 so as to carry out scouring operations on metal ware such as pots and pans, and knives and forks, also for burnishing such articles. We claim:
